To (ZZZ 'whom'z't may concern."

Be it known that I EnwAnDL. 001), a: citizen of the United States, and a resident of Detroit, county of Vayne, and State of Michigan, have invented certain new and useful Improvements in lVindo'w Stops, of which the following is a full, clear, concise, and exact description, such as will. enable others skilled in the art to which the invention relates to make and use'the same, reference being made therein to the accompanying drawings, which form a part of this specification.

The presentinvention relates to window stops, the primary object being to provide a simple, inexpensive device whereby ample protection isinsured against entrance by unauthorized persons aiid'wherehy ventila tion is at the same timefreely permitted. The invention also aims to provide a device of the class set forth which may be easily installed eitheras initial equipment or as an accessory and regardlessof whether ornot any of the usual types of fasteners are present or retained.

As will be understood as the description progresses, the invention is applicable not' only to the] ordinary window wherein both upper andlower sliding sashes are present, but also to windows.includingbut a single sliding sash and to slidable closures generally whether glazed or not'.

In the drawings, Fig. 1 shows a window; equippedlwith a preferred embodiment of my invention, the sashes being closed; Figs. 1 1 and 1 are like views, the sashes be-,' ing in different positions; Fig. 2 is a central vertical section through the socket showing the parts in assembled relation; Fig. 3 is a view looking from the left in Fig. 2, parts I being broken away; Fig. lris a section on line H ofFig. 2; 5 is a perspective viewot' the socket member; and Fig. 6 is a fragmentary perspective view showing a modification.

The usual window frame appears at l,

the lower sash at 2, the upper sash at 3 and one of the side rails of the latter is bored out or otherwise formed to receive a socket member 4 which may be attached thereto by screws 5 passing through an annular butturned flange 6 of the socket andinto the wood of the side rail. It is obvious that any suitable means of attachment of the socket may be used, such, for example, asby rivetangular distance from the outlet of the groove 8 to a point approximately 180 therefrom wherethey terminate in a depression 10. i V 1 l Arranged to be detachably received in the socket'is a cylindrical 'pintle 15 having its end portion provided witha projection 16 adapted topass through the groove 8 and to seat against the various surfaces which go to make up the end face of the socket.-

The pintle is provided with a suitable handle or arm 17 ,that shown being ad-- mirably suited for the purpose and being formed of stamped ribbed metal bent double about the pintle and spot-welded together atintervals in its length and to the pintle as indicated at-18,:or one such as shown at 17 in Fig. 6 may be employed." A suit able resilient element, such as the thin warped disk 19, is interposedsbetween the handlegl7 and-the flange 6. and preferably overlies the heads of the, screws 5, or a helical spring 20, Fig. 6, may be used.

, It will be noted from F igs. 2*and 4t that thefouter end portion of the bore 7 of the socket member is prefer-ably, although not necessarily, somewhat enlarged or flared outwardly and downwardly along the lower wall as at 21. .f

Thesocket is preferably assembled on the sashwith thegroove8 substantially lowermost; and the .pintle. is inserted. and suflicient pressureapplied to compress the disk or spring to allow the projection 16 .toiclear the e-ndwall of the socket, Upon the handle then being turned angularly. the spring snaps the projection outwardly behind the abutment at the base of the corresponding cam surface 9. In this connection it will be understood that it is desirable from a commercial standpoint that therebe two sets of these surfaces, as shown, in order that the device may be mounted on either the right, or the. left side rail of the sash as desired, but one of the surfaces may obviously be omitted. Inany event, it will mg in theevent the sash is of the metal1' be seen that the pintle cannot again be removed from the socket until the spring-iscompressed to permit the projectionito clear the abutment at the base of the camand 5 then only in the eventthe handle is swung to hang substantially directlydownward to bring the projection in line with the groover.

If it is desired to secure ventilation, the handle is swungto the position-iindicated in Figs 1 1 and 1 that is, it is swung substantially-4 1809' from theposition in which the projection registers with the groove, during 1 which movement the projection "16f. ridesz'atlie :cam Si until'iit 'is' fi'nally re:

ceived in: itlIB depressionlO to th'e'rebiy retain-" the .handle in. what 1 might be termed the" ventilating;-positionz. The distance from-the axis :of :the' socket torthe adjacent upper sur face-ref: the top railfof the'lo-We-r sash when 20s the. window is closed is'preferably, but 1100 necessarily, nearly equal to the length of!- the handle 17, sayvsix or eight inches, therefore it Will be seen that, in theinstance-A first stated; the upper: sashzmay be* lowered fsubstantially; six' inches; (Idi t: 1 -),'or the loWer-- sash: may: be 2 raised i substantially inches (Fig.1; 1), orithe-itotal opening may heap-portionedbetween: the *top and bottom as=desired (Eigstlt').

Likewise; it: will be evident that the open ingds insufficient to? permit the entrance of an intruder, nor' will sitb'e' possiblefor himto insertan arm to -manipulate tlrelrandlesufii'ciently to :V'lth-dTZIW it from the 1 socket, :1 for the reason that the*saslumustbenearly closedbefore: the:- handle can bewswung to bring the. projection 16 into registration withthe*groove;8; j V

Alsoy; in the event a; tool is inserted: to

40 pry? thethandle iinwardly the end portion of theipint'le-rnearestztlre handlewvill be pressed down into the: enlargement 21 of the-- borewith a" resulting tendency to .jamthe parts, The bore mightzof course Abe-made ofbylindrical 'crossesection throughout:

When zit is desired tos-irelease thed'e'vice; the-handle istswung: around'inearly; into the position indicated in Fig. 1, whereupon a" personvin tlierinsi'de of'zthefroom, by pressing inwardly to overcomes the springi and by a further slight angular turn to align the pro jectionr1l6 withthe'groove 8,4mayreadily remove-the handle,

It will be clear that th'e device-maybe" changed within: considerable limits without departing from the spirit fof Y the invem tion.

Iclaim: 1; In; combination with a frame having an opening 'and a slidable closure therefor,

a-1socketimember; carriedi'by the closure;- a

pintle cooperating therewith and "swingable about an axis. at right angles :tothe plane my thereof and J removable therefrom when the closure" isssubstantially closed, and F means for preventing the stop from being removed fromtheclosure when the latter is open to an a-ppreciab'le' extent.

8. As an article of manufacture, a window stop embodying a socket adapted to be attached to a sash, a second member including a pintle and an arm, said pintle 10 arranged to be received in and supported by said socket and said second member being adapted for angular movement about the axis of said pintle, and means for preventing the second member from being disengaged from said socket except when said arm is in a predetermined angular relation in respect thereto.

In testimony whereof I aflix my signature.
